Most owners only think about servicing when something goes wrong. The chassis manufacturer provides maintenance schedules for the engine, the coachbuilder focuses on the body, windows, and roof, Victron documents batteries and inverters, Alde explains the heating system, Dometic covers the refrigerator — but no one brings all of this information together in one place.

This guide is not intended to teach you how to rebuild an engine or overhaul a transmission. Its purpose is to show you what to inspect, when preventive maintenance should be performed, and why prevention is always less expensive than repairs — whether you own a Phoenix, Morelo, Concorde, Carthago, Hymer, or any other motorhome.

How to Use This Guide

A motorhome maintenance schedule can be divided into two categories:

For every maintenance item, it is useful to understand how the system works, the most common causes of wear, the recommended service interval, the approximate cost of preventive maintenance, and the approximate repair cost if maintenance is neglected.

Specific service intervals vary between chassis and motorhome manufacturers. This guide serves as a general framework that you can adapt using your own vehicle's service documentation.

Service Intervals by Mileage and Time

The intervals below are general guidelines. Always cross-reference with your chassis manufacturer's official documentation.

Every 20,000 km (12,500 mi) or 1 Year

Every 40,000 km (25,000 mi)

Every 60,000 km (37,000 mi)

Every 80,000–100,000 km (50,000–62,000 mi)

Every 100,000 km (62,000 mi)

Every 2 Years

Every 3–5 Years

Never Underestimate Roof Seals

Important

Inspecting the roof seals and all roof penetrations — including the air conditioner, solar cable entries, vents, and antennas — typically costs only a few hundred dollars or euros. Ignoring small leaks, however, can result in water damage that remains hidden until stains appear on the ceiling or structural wood begins to soften. Repair costs can quickly climb into the tens of thousands, and in severe cases the motorhome body may be considered beyond economical repair.

What Comes Next?

This overview is only the introduction to a much larger knowledge base. The following chapters examine each system in detail:

Our goal is to create one of the most comprehensive preventive maintenance guides for motorhomes — a resource that helps owners extend the lifespan of their vehicles, improve reliability on the road, and avoid unnecessarily expensive repairs.

Maintenance Logbook and Detailed Guides

This article provides only the condensed framework of a complete maintenance schedule. The accompanying chapters explain each system in detail, including how to keep your own maintenance logbook and why, unlike a conventional passenger car, a motorhome requires regular monitoring not only of the chassis but also of the living area and all onboard systems.

A practical maintenance checklist for the Iveco Daily chassis — including mileage- and time-based service intervals, annual inspections, and quick symptom-based diagnostics — is also available as a downloadable PDF: Iveco Daily Maintenance Logbook.

The complete introductory article, together with all checklists and detailed chapters covering the engine, transmission, brakes, LiFePO₄ batteries, solar system, water system, LPG installation, heating, air conditioning, winterization, and spring recommissioning, is available on the blog: Motorhome Maintenance Schedule — The Complete Preventive Maintenance Guide.

Frequently Asked Questions

Why is preventive maintenance always cheaper than repairs?

Because most major mechanical failures develop gradually. Replacing fluids, filters, seals, or worn components on time is only a fraction of the cost of rebuilding an engine, transmission, or repairing extensive water damage. The key is catching problems when they are still inexpensive to fix — not after they have cascaded into something much larger.

How often should LiFePO₄ batteries be checked?

A visual inspection should be performed regularly. A full charge to 100% State of Charge (SOC) every few weeks or months — depending on usage — helps maintain accurate battery calibration and monitoring. On the Phoenix, I charge the Victron LiFePO₄ NG batteries to 100% at least once a month when the vehicle is in storage, so the SmartShunt always reports accurate capacity data.

Do service intervals vary between motorhome brands?

Yes. While the general maintenance principles are universal, manufacturers may specify different service intervals for the chassis, living area, and onboard equipment. The intervals in this guide are based on Iveco Daily recommendations and general coachbuilder practice. Always follow the recommendations for your specific vehicle and consult your manufacturer's documentation.
